DC and HS are apparently neck-and-neck in terms of gains for the GT...
again this is claimed yet there are no dynos posted ANYWHERE as proof.
I wont trust HS until I see some dynos
I just know there are way too many mods that should work and dont. IMO if they cant post a dyno then there may be a reason why.
butt dyno opinions of oh it felt faster dont mean anything to me
